It’s true that our drinkware is unbreakable, but to keep symGLASS products looking their best, please follow these safe handling measures:

Cleaning: Avoid using steel wool or other abrasives on symGLASS.

Dishwasher Use: When cleaning symGLASS products, we recommend using only the top-rack of the dishwasher, and normal wash cycle settings. Avoid direct contact with, or close proximity to, the heating element, and secure your symGLASS to prevent contact scratches from other dishes.

CAUTION: If you are enjoying symGLASS products outdoors, be aware that sunscreen, citrus, and some essential oils may cause surface clouding or discoloration. If using sunscreen, wash hands prior to handling your symGLASS products.

If you do experience this, it is strictly a cosmetic issue and your glass is still perfectly safe to use. Try hand-washing with mild soapy water or a gentle detergent. Avoid abrasives or harsh chemicals.

If you expect to handle symGLASS after applying sunscreen, we recommend using one of our Opaque White glass options.
